The Elephant in the Universe: 100-year search for dark matter Author: Govert Schilling The Big Bang's Clues: Non-Baryonic Matter and Failed Candidates Headline: Cosmic Evolution Demands New Matter; Neutrinos Fall Short The universe's evolution from the smooth, hot state after the Big Bang to its current clumpy structure of galaxies and clusters requires far more gravity than visible matter can provide. Everything we know, from atoms to stars, is classified as baryonic matter. However, the nature of dark matter must be different; it cannot be composed of atoms and is thus termed non-baryonic matter. In the early 1970s, Albert Bosma used radio telescopes to observe hydrogen gas far beyond visible galactic edges, confirming the widespread anomalous rotation curves found by Rubin and Ford. Early dark matter candidates included neutrinos, but their light, fast-moving nature ("hot dark matter") meant they would clump on vast scales first, contradicting observations of early small clumps. This led to the conclusion that dark matter must be "cold" and slow-moving. 1959

The Elephant in the Universe: 100-year search for dark matter Author: Govert Schilling Headline: Particle Physics and Simulations Hunt for the Elusive WIMP The concept of cold dark matter, championed by cosmologists like Jim Peebles, describes particles that interact primarily through gravity but lack electrical charge, meaning they don't interact with light, magnetism, or strong nuclear forces. Their only potential interaction is a rare "bump" into an atomic nucleus via the weak nuclear force. This led to the theoretical candidate known as the Weakly Interacting Massive Particle (WIMP). Experiments at facilities like CERN's Large Hadron Collider, with its massive underground detectors, attempt to create and detect these WIMPsthrough high-energy particle collisions, though none have been found yet. Complementing this, computer simulations, such as IllustrisTNG, successfully model the universe's evolution from its smooth beginning to its current clumpiness, but only when incorporating cold dark matter with specific properties, guiding the ongoing search. . 1957

The Elephant in the Universe: 100-year search for dark matter Author: Govert Schilling Challenging Dogma: MOND and the Exclusion of MACHO Headline: Alternative Gravity, MOND, Contests Dark Matter Theory as MACHOs are Ruled Out Amidst the elusive search for dark matter, alternative theories have emerged. Mordehai Milgrom and his colleagues developed Modified Newtonian Dynamics (MOND), proposing that our understanding of gravity is flawed at galactic scales, thereby explaining rotational curves without needing dark matter. While some like Jeremiah Ostriker dismiss it, others such as Stacy McGaugh acknowledge its surprising success in fitting observational data. Gravitational lensing, as demonstrated by the Bullet Cluster, offers strong evidence for dark matter by showing separate distributions of mass and gas during galaxy collisions, challenging MOND. Meanwhile, another dark matter candidate, Massive Compact Halo Objects (MACHOs)—very massive, compact objects in galactic halos—was extensively searched for in the 1990s using gravitational microlensing. Despite significant effort, these searches yielded no detections, effectively ruling out MACHOs as the primary form of dark matter. 1958

The Elephant in the Universe: 100-year search for dark matter Author: Govert Schilling  The Enigma of Dark Energy and Einstein's Lost "Blunder" Headline: Universe's Acceleration Reveals Dark Energy, Validating Einstein's Constant Just as the search for dark matter intensified, cosmology faced a new puzzle: in 1998, two independent teams discovered that the universe's expansion is not slowing down but is, in fact, accelerating. This unexpected finding led to the concept of dark energy, a mysterious vacuum energy in empty space, as the force driving this acceleration. This revelation meant that visible baryonic matter accounts for only about 4.9% of the universe, with dark matter making up 26.6%, and dark energy a staggering 68.5%. Ironically, this unexpected acceleration harked back to Albert Einstein's "cosmological constant," a term he had introduced into his equations as an accelerating force to maintain a static universe and later deemed his "biggest blunder." The discovery of dark energy suggests Einstein may have had a profound, albeit unrecognized, foresight. 1941

Analysis of its tiny temperature and density fluctuations precisely determines the universe's composition, independently confirming the need for both dark matter and dark energy even without other observations. Meanwhile, the direct hunt for WIMPs continues in deep underground laboratories like Gran Sasso in Italy, where massive, shielded experiments containing materials like liquid xenon aim to detect the exceedingly rare collisions of dark matter particles with atomic nuclei. These "xenon wars" have, to date, yielded "null results," intensifying the mystery. Only the DAMA experiment, using sodium iodide crystals, claims to have detected a seasonal dark matter effect, but its results remain unconfirmed by other teams. 1952

With direct WIMP detection still elusive, physicists explore highly speculative theories: primordial black holes (black holes born in the Big Bang), fuzzy dark matter, or decaying dark matter, though these lack observational evidence. Theoreticians like Erik Verlinde propose "emergent gravity," suggesting gravity is not fundamental but arises from a deeper reality, which could imply dark matter doesn't exist at all. The ongoing search involves particle physics, underground experiments, powerful telescopes like the future Extremely Large Telescope, and the International Space Station's AMS experiment looking for antimatter signals, as scientists continue to refine theories and devise new ways to observe the unseen 1956

A decade later, his student, Jan Oort, further identified the Milky Way's rotation and, by studying the up-and-down motions of stars, made an early estimate of dark matter in the galaxy's central plane. Building on this, Swiss astronomer Fritz Zwicky observed the Coma Cluster in California, using redshift to determine galaxy motions. He concluded there was more mass and gravity than visible, coining the German term "dunkle Materie," meaning "dark matter." These early 20th-century findings laid the groundwork for the ongoing dark matter mystery. 1957

This theoretical need was then powerfully confirmed by the observational work of American astronomer Vera Rubin and her colleague Kent Ford throughout the 1970s. Studying distant galaxies, including Andromeda, they discovered that stars on the outer edges rotated at unexpectedly high, constant velocities, rather than slowing down as predicted. This "flattening the curve" of rotational velocities offered the first concrete proof for the existence of dark matter, whose gravity was necessary to prevent galaxies from flying apart. 1958

Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature. Physicists have devised huge, sensitive instruments to search for dark matter, which may be unlike anything else in the cosmos―some unknown elementary particle. Yet so far dark matter has escaped every experiment. Indeed, dark matter is so elusive that some scientists are beginning to suspect there might be something wrong with our theories about gravity or with the current paradigms of cosmology. Schilling interviews both believers and heretics and paints a colorful picture of the history and current status of dark matter research, with astronomers and physicists alike trying to make sense of theory and observation. 2016 NGC 24

IS DARK MATTER FROM BEFORE THE BIG BANG?  8/8: The Elephant in the Universe: Our Hundred-Year Search for Dark Matter by  Govert Schilling  (Author), Avi Loeb  (Foreword) https://www.popularmechanics.com/space/a64379333/dark-matter-older-than-universe/ https://www.amazon.com/Elephant-Universe-Hundred-Year-Search-Matter/dp/0674248996 In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature. Physicists have devised huge, sensitive instruments to search for dark matter, which may be unlike anything else in the cosmos―some unknown elementary particle. Yet so far dark matter has escaped every experiment. Indeed, dark matter is so elusive that some scientists are beginning to suspect there might be something wrong with our theories about gravity or with the current paradigms of cosmology. Schilling interviews both believers and heretics and paints a colorful picture of the history and current status of dark matter research, with astronomers and physicists alike trying to make sense of theory and observation. 2009 DARK MATTER AND DARK ENERGY
